What is Formula RPD?
Formula RPD is a new racing class based on a car built by Walt Boyd Racing in Apple Valley, California. RPD is an acronym for Road courses, Paved ovals, and Dirt ovals, the three different types of venues the car is designed to run on.
General description of the car:
Open wheel, rear (mid) engine, powered by a Kawasaki ZX14 engine
Independent suspension front and rear
Inboard coil-over springs/shocks
Tig welded chrome moly steel tube frame, with roll cage
Lightweight, hand laid-up, fiberglass body
Bumpers front and rear, nerf bars inside side pods
Quick-change ratio, adjustable assist, power rack-and-pinion steering
10.5” scalloped, vented rotor brakes
Chain drive with torque biasing differential
13” x 8” front wheels, 13” x 10” rear wheels
Two midget radiators (one in each side pod)
Adjustable wings front and rear
Purpose made, owner configurable, ECU/data display

What is the Concept?
The concept is a serious racecar that is within the means of middle-class racers who have a true passion for the sport. A serious racecar in this context means one with more speed, acceleration, cornering, braking than you would ever experience in a production car (short of the most extreme high-performance cars that cost astronomical amounts of money),

a racecar that is purposefully designed to run on road courses, paved ovals, and dirt ovals:
Six-speed gearbox, torque sensing differential, and big brakes (features need on road courses)
Roll cage, bumpers and nerf bars, quick change drive ratio capability (features needed on paved ovals)
Short wheelbase, lots of wheel travel, fast, adjustable assist power steering with lots of steering lock (features need on dirt tracks)
Six-speed gearbox, torque sensing differential, and big brakes (features need on road courses)
Roll cage, bumpers and nerf bars, quick change drive ratio capability (features needed on paved ovals)
Short wheelbase, lots of wheel travel, fast, adjustable assist power steering with lots of steering lock (features need on dirt tracks)
a racecar that has a high-performance engine/clutch/gearbox package that makes both initial cost and maintenance costs a small fraction of what those costs normally are,
a race car that is designed for driver safety—the design incorporates many driver protections—yet is readily repairable. The tube frame is very strong, but there are crushable (and readily replaceable) components all around.
a “spec” race class, but one with very few rules, allowing competitors total freedom within a wide range of adjustments,
a race class for drivers whose ambition is to move eventually into IndyCar, IMSA, or even Formula 1, but don’t have the financial resources to pursue the usual paths to those goals. Formula RPD is a way to get both road race experience and rear-engine experience, not to mention all the valuable techniques of short-track pavement and dirt racing,
a racing class that makes it easier for competitors to get sponsors than would be the case with a strictly road racing class. In oval track racing there are spectators. That’s not the case with road racing except at the highest levels of the sport.

About Engines
You can bring us an engine, and we will install it. Or we can sell you one.
We buy used engines on-line for typically $4,000 to $5,000, plus shipping. The cost of engines varies depending on the year and mileage. Shipping varies depending upon where it’s coming from. We will sell you one for 10% over our cost. We sell engines with absolutely no guarantee. (We can cut the oil filter up and see if there is any metal in it.) It’s your choice to gamble and run it as-is or rebuild it and do whatever modifications you want (within the rules, of course), then bring it back, and we will install it.
Anticipated Race BudgetsBased on actual experience with other open wheel, motorcycle-engine based classes, we estimate that you should be able to field a competitive car for somewhere between $500 and $1,500 per race (not counting offsetting money you might win). Obviously, there are a lot of variables. One would be where you live relative to where most of the races are. Another would be how much maintenance and repair work you do yourself.
We haven’t finalized tire rules yet. It’s difficult—not necessarily impossible—to make tire rules that totally eliminate the advantage of an unlimited tire budget. We’re working on that.

What will it cost to get into this new racing class?
We are going to offer a rent-to-purchase plan whereby a buyer can rent a car initially and apply the rental fees toward the ultimate purchase. The rental cars will be fully assembled, of course. We are going to sell the first 10 cars at about half of what they ultimately will cost. We haven’t established a price for a turnkey car, which is what the rental cars will be, but it will have to be close to $100,000. (Racecars are rarely sold that way because the finish assembly adds so much to the cost, and even with a spec class there are many things an owner can personalize.)
The rental fee/purchase price will be individually negotiated because it involves a lot of issues: How much racing experience does the driver have? Who transports the car to the track? How are the tire costs handled? Who does the maintenance and race prep (and what kind of experience do they have)? But the cost of the first 10 cars will be in the range of $50,000, with the per race rental in the vicinity of $2,500. There will be a crash damage deposit required, but whatever is not used to cover crash damage can be applied to the purchase cost.
The rent-to-own program will amount to a big capital investment by us, but a smokin’ deal for the first 10 buyers, because we will be selling cars way below their actual value.
Prior to our first race we plan to have three practice sessions, one on a road course, one on a paved oval, and one on a dirt track. We will rent the tracks and bring two or three cars. People seriously interested can get some track time without putting a lot of money at risk. (We will require some security deposit to cover potential crash damage, but not a huge amount, only enough to discourage recklessness.) And we are lining up some experienced drivers to be at the track to coach drivers who have no experience on the particular type of racetrack. (Not many drivers are experienced on all three of the different venues this class is designed to run on.)
Note from Walt BoydThis is obviously a very ambitious venture. I have undertaken this whole project in my “retirement” years, largely out of love of the sport, having seen the need for a racing class that affords aspiring drivers who don’t have a whole lot of money, a way to work toward Indy or even F1.
While I think there is profit potential in building and selling these cars, or in running a racing association based on this formula, I’m too old to be motivated by that; I just want to see all this effort come to fruition. I would welcome the participation of anybody who can bring any skills or experience to the table. If you are an experienced driver, car owner, racing organization official, race promoter, publicist, or anything else that could help, please contact me.
